' END-GATE ron MINE-cans.

Specification of Letters Patent.

Patented Nov. 9, 1909.

To all whom it may concern:

Be it known that l, Louis F. BRUBAKER, a citizen of the United States of America, and resident of Cambridge, county of Guernsey, and State of Ohio, have invented certain new and useful Improvements in End-Gates for Mine-Cars, of which the following is a specication.

This invention relates to improvements in dump-cars for mines, and more particularly to an end-gate for such cars; and it consists in the particular construction, arrangement and combination of parts which will hereinafter be fully described.

The object of the invention is to provide a swinging end-gate for mine-cars, said endgate having a lever-operated lock or bolt which may be conveniently manipulated to elect the opening of said end-gate and which locks automatically when the car assumes a horizontal position.

A further object is to provide opening and closing means for the end-gates of mine-cars, which means is extremely simple and inexpensive in its construction and which is but little liable to become out of order.

In describing the invention in detail, reference is herein had to the accompanying drawing, forming a part of this specifica.- tion, in which- Figure 1 is a side elevation of a mine-car equipped with the present invention, showing said car in inclined, or dumping, position; Fig. 2 is a top plan view of the same; Fig. 3 is an end view ot the same, showing the invention in front elevation; Fig. 4t is an enlarged vertical sectional view on the line 4 4, Fig. 3; and-F ig. 5 is a perspective view ot an end portion of the bottom of the car-body, showing a modiiied form ot clip or catch-plate overlying the draw-bar.

Referring to said drawing, in which like reference characters designate like parts throughout the several views-1 indicates a ear-body and 2 the end-gate, the latter being sustained in an outwardly-swinging position in any suitable manner, as by a transverse rod or bar 3 having its ends suitably supported at opposite sides of said car-body, to which rod or bar said end-gate is connected, or from which it is suspended, by means of straps 4. For admitting of outward swinging of said end-gate 2, the ends of said rod 3 may be pivotally mounted, or the straps 4 may be rotatable upon said rod. Fixed collars 5 carried by said rod abutagainst said straps, preventing lateral movement of the end-gate with respect to said rod.'

Fixed to the under side of the bottom 10L oi' the car by means of bolts G are the horizontal inturned terminals 7 of a U-shapcd clip 8 which straddles the body of the usual draw-bar 9 at a point adjacent to the outer face of said end-gate when the latter stands in normal position said clip and said draw bar each giving rigidity to the other. An upwardlyand inwardly-beveled lip 10 is formed on the horizontal, or draw-bar-overlying, portion of said U-shaped clip 8, which lip is adapted to coact with the beveled end 11 of a vertically-movable bar 12 for eecting the self-locking or fastening of said endgate when it returns to its normal position after the load has been dumped. Said bar l2 has its upper end seated within or against the lower end of a coil-spring 13 which is mounted in a socket 14 in a socket-plate 15 rigidly mounted upon the end-gate 2, while its lower or beveled end 11 normally lies behind and in engagement with the rear face of the lip 10. Said bar 12 has a longitudinal slot 16 therein which admits of movement of the bar along a pin, bolt, or screw 17 whose point is fixed in said end-gate and which at its outer end is directed through a keeper 18 mounted upon said end-gate in such manner as to embrace and guide said bar. Pivotally connected to said bar 12 at a suitable point, as intermediate the keeper 18 and the socket-plate 15, is the biturcated end of a substantially horizontal lever 2O which is pivoted or ulcrumed at 21 in a keeper 22 carried by said end-gate, as shown.

In practice, when the car 1 has assumed a dumping position, as on an incline or dump 23, the free end of the lever 2O is depressed by hand, which action elevates the bar 12 against the tension ot' the spring 13 until its point 1l becomes disengaged from the lip 10, when the pressure of the load forces the end-gate 2 outward, admitting of the release of said load. As the car again assumes its normal position, the end-gate gravitates back to its normal position, and, in doing so, the bevels of the lip and of the lower end of the bar coact to elevate the latter and to allow it to pass over and to assume a locking posiplate straddling the draw-bar 9 and having its ends bolted to the bottom la of the car. An integral upwardlyn and inwardly-beveled lip 10a is provided on said plate 24,:15 shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a dump-ear having a drawbar7 a swinging end-gate, a vertically-movable springpressed bar mounted on the outer face of said end-gate adjacent to its lower edge and having a beveled lower end, a member mounted upon the car floor in straddling relation to said drawbar whereby rigidity is maintained in both said member and said 15 the drawbar-overlying portion thereof behind which the beveled end of said bar normally rests, and a lever for elevating said 20 bar to withdraw its beveled end from engagement with said lip.

In testimony whereof I aX my signature in presence of two subscribing witnesses.
